It is an open question what has constrained macroevolutionary changes in marine animal diversity on the time scale of the Phanerozoic. Here, we will show that supernovae appear to have significantly influenced the biodiversity of life. After normalizing diversity curves of major animal marine genera by the changes in the area of shallow marine margins, a close correlation between supernovae frequency and biodiversity is obtained. The interpretation is that supernovae influence Earth's climate, which controls the ocean and atmospheric circulation of nutrients. With this, supernovae influence ocean bioproductivity and are speculated to affect genera-level diversity. The implication is a surprisingly influential role of stellar processes on evolution.
在显生宙时间尺度上,是什么限制了海洋动物多样性的宏观进化变化,这是一个悬而未决的问题。在这里,我们将表明超新星似乎对生命的生物多样性产生了重大影响。在用浅海边缘面积的变化对主要海洋动物属的多样性曲线进行归一化之后,得到了超新星频率与生物多样性之间的密切相关性。其解释是超新星影响地球气候,而地球气候控制着海洋和大气的养分循环。由此,超新星影响海洋生物生产力,并推测会影响属级多样性。这意味着恒星过程在进化中有着惊人的重要作用。
